“…The North Pennine Batholith has been explored as a potential source of heat in recent years, with the likelihood it will be used for direct heat use and electricity generation (e.g., [6,33,34]). Recent 3D geological modelling suggests that temperatures of 100 • C can be found at depths of ~3 km ( [34]). A doublet scheme, connected by natural [6,35] or un-natural fractures (an enhanced geothermal system), could therefore be used for direct heat use.…”

Heat exchangers are vital to any geothermal system looking to use direct heat supplied via a district heat network. Attention on geothermal schemes in the UK has been growing, with minimal attention on the performance of heat exchangers. In this study, different types of heat exchangers are analysed for the Cheshire Basin as a case study, specifically the Crewe area, to establish their effectiveness and optimal heat transfer area. The results indicate that counter-current flow heat exchangers have a higher effectiveness than co-current heat exchangers. Optimisation of the heat exchange area can produce total savings of £43.06 million and £71.5 million, over a 25-year lifetime, in comparison with a fossil-fuelled district heat network using geothermal fluid input temperatures of 67 °C and 86 °C, respectively.

“…Chen et al (2019) suggests the influence of groundwater and advection on the performance of deep BHEs to be minimal. As such, heat flux in the rock was modelled as (e.g., Nield and Bejan, 1992;Howell et al,2021):…”

“…The Moho interface is the geological boundary between the earth's crust and the mantle, and the Curie interface can be considered as an isothermal surface, with a temperature of 580°C (Tanaka et al, 1999;Elbarbary et al, 2018), which is used as a limiting condition when getting the thermal field underground. The temperature field can be solved by the equation (Howell et al, 2021):…”

Geothermal resource is indispensable as a clean, renewable, stable and cheap resource. Nowadays in China, the Gonghe Basin, located in northeastern Qinghai Province, has been thought to be a promising geothermal area. To explore geothermal energy potential in and around the Gonghe Basin, geophysical means including magnetic and gravity methods were used to plot distribution. Firstly, we inversed Moho depth and Curie point depth in and around the basin using gravity and magnetic data, respectively, through an improved Parker-Oldenburg algorithm. Secondly, seven different thermal models were established, considering radiogenic heat, basement depth, anomalous heat source and simulated corresponding temperature field and heat flow. These were analyzed numerically and we found the high heat flow in the Gonghe Basin coacted with radiogenic heat, an anomalous heat source and conductive heat. The distribution of seismic activities indicates that the Langshan-Wuwei-Gonghe Fault might have provided channels for transporting heat effectively.
